If you need any proof that X-Men: Days Of Future Past was a blast to shoot, look no further than this video.
In an interview promoting the new film, James McAvoy and Michael Fassbender reveal that they've been studying their contemporaries so closely that they can nail Patrick Stewart and Ian McKellen's accents.
This follows the revelation in an Esquire interview with MIchael Fassbender that, during filming, the cast got kitted out with BB guns and chased each other around the trailers.
Being an blockbuster movie actor appears to be rather good fun. Who'd have thought it?
